LOZENGE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 264,528, datedSeptember 19, 1882.

Application filed March 30. isse. (N 5.0.1.1.

To all whom tt mag concern Beit known that 1, CHARLES H. HALL, ofChicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Lozenge-Machines, of which thefollowingis a description, that will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon,forming a partof this specification. V

This invention relates to improvements in that class of lozenge-machinesemploying a series of cutters having pistons moving on the interior ofthe same for the purpose of expelling the lozenges therefrom, the facesof said pistons being of an ornamental or word char- .acter, whereby theconfection is embossed or Fig. 2.

lettered before being forced out of the cutters; and it consists ofcertain novel features in the construction, arrangement, and operationof the several parts, as will be hereinafter more fully set forth indetail.

Figure 1 is an end elevation of the cutting mechanism proper, with theoutside supporting frame-work broken away in the plane 1 1, Fig. 2 is arear elevation;-Fig. 3, a vertical transverse section in the plane 3 3,Fig. 2. Fig. 4 is a front elevation of the cutting apparatus, showingthe mechanism for transmitting motion and power; Fig. 5, a verticaltransverse section in the plane 5 5, Fig. 4. The illustration anddescription are confined to the cutting mechanism proper and immediateparts, the parts broken away being of the usual construction andoperation common to this class of machines.

Referring to the drawings, A representsthe supporting frame-work; A, theendless apron which delivers the dough or paste to the series of cuttersat; A the apronwhich receives and carries away the waste or scrap A theboard apron which moves the trays A into position to receive the goodsas they are dropped from the delivery-tray A A is a cross-bar bolted toframe A, and securing the top ends of guides a a The cross-head B isadapted to carry theseries of cutters at, having the pistons a moving onthe interior thereof, as shown in Fig. 3 ot' the drawings. The ends ofthe cross-head are adapted to slide into thejaws a a and as the cuttingmechanism is set on an incline the weight of the cross-head serves toretain itself in place, thereby enabling the same to be convenientlyremoved for repairs or other purposes. The jaws a a have a verticalmovement on the guide-rods a a and are attached to the lower ends of theconnecting-rods B B", the upper ends of which are connected to thecranks B B, placed upon the .ends of the driving-shaftB through themedium of which motion and power are transmitted to the cuttingmechanism.

The scriesot' pistons a, moving on the inside of the cutters, areprovided with the rods or stems b, the upper ends of which are threadedand pass through and project above the perforated plate I), where theyreceive the nuts 11 which adjustably secures them in relation thereto.The nuts b are placed at intermediate points between the plate I) andthe crosshead B, and serve to regulate the tension on the springsb,which are placed upon that portion of the piston-stems between thenuts b and the under side of the plate b. The sleeves b are placed upon.the piston-stems to prevent the springs from catching on the threadedparts, and also to allow a free action of the same. These springs serveto give the pistons an independent adjustment with reference to eachother, and adapt these parts to accommodate themselves to any uneventhickness in the sheet of dough. The piston-stems are provided with theshoulders b which, in connection with the plate a", serves to gage thethickness of the lozenge. The plate a, is raised or lowered'by means ofthe bolts w placed at each endof the cross-head, and is prevented fromhaving a lateral movement by means of the bolts a placed at each end, asshown in Fig. 3 of the drawings.

The plate 0 is secured so as to rest upon the upper ends of thepiston-stems, and which, when brought in contact with the bridge 0, hasthe effect of forcing all the pistons down at the sametimeand expellingthegoods which have been picked up by the cutters. The bridge G issusceptible of avertical movement, the ends being connected to the lowerends of the arms 0 The upper ends of these arins are adjustabl y securedto the guide-rods a a Dld by which arrangement the bridge 0 may bebrought to the required position.

By means of the elliptic springs (1 placed between the cross-head B andthe plate I) and at each end of the same, all the series of cutters aresimultaneouslyraised from the cutting-bed C 0 represents theclearing-plate.

Placed upon the driving-shaft B are the cams D D,which have frictionalcontact with the upper ends of the rods D D the lower ends beingattached to the bridge 0, as shown in Figs. 4 and 5 of the drawings.

1) D are spiral springs encircling rods D D and resting on the cross-barA, then imparting to said rods an upward tendency by reason of theirtops bearing under ashoulder, By this means the rods D D are held incontact with the under side of the cams. This arrangement is for thepurpose of forcing down the pistons beyond the cutting-edge of thecutters the second timein each revolution, the first downward movementof the pistons being caused by the plate 0 comingin contact with thebridge 0. This dual movement of the pistons in each revolution insures amore certain clearance of all the goods from the cutting mechanism.

The receiving-tray A is adapted to have an automatic reciprocatingmovement, the tray being brought underneath the cutters when they are onthe upward stroke at the proper time to receive the goods when they areexpelled by the descending pistons. This movement is accomplished bymeans of the swinging arms D D which are placed at each end of thecutting mechanism. The upper ends of the swinging arms are pivoted tothe brackets d d, which project outward from the framework, as shown inFig. 1 ot' the drawings. The lower ends of the swinging arms are rigidlysecured to the sides of the tray, the extreme upper ends being bent overat right angles and having frictional contact with the upper ends of thetn mbler-rods dd ,\vl1ich have avertical bearing in the bracketsdd, asshown in Fig. 1 of the drawings. The lower tubular ends of thesetumbler-rods have a threaded interior for the reception of the upperends of the threaded extensions d (1 the lower ends having astep-bearing on the projectionsff. (Shown in Figs. 1 and 2 of thedrawings.) By means of these threaded extensions the tumbler-rods areshortened or lengthened, as may be required, in gaging the throw ortravel of the receiving-tray. The inner ends of the projectionsfareattached to thejaws a a of the cross-head and travel with the same, andon the upstroke cause the upper ends of the tumbler-rods to strike theunder side of the upper bent-over ends of the arms D D forcing the sameupward in the arc of a circle, and thereby imparting a correspondingmovement of the lower ends attached to the receiving-tray A and movingthe same underneath the cutters to receive the manufactured goods anddischarge them into the trays A. One end of the springs F, of whichthere are two, is attached to the arms D D, the opposite ends beingattached to a part of the stationary frame not shown and assisting theforce of gravity in returningthe receiving-tray to a normal position.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a lozenge-machine, the combination of the jaws a a cross-head B,rods B B cranks B B and shaft 13, the jaws at a" sliding on guides a, aall of said parts being inclined out of the perpendicular, so that thecross-head carrying the cutters rests in the jaws and is secured thereinby its own weight, substantially as and for the purposes set forth.

2. In alozenge-machine, thejaws a a ,crosshead B, rods B B cranks B Bshalt B the cross-head B having cutters a, and pistons a, provided withstems b, in combination with the adjustable plates 0 and b, all of saidparts being set on the incline and arranged in the manner and for thepurposes set forth.
